Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
2. The display panel according to claim 1, wherein in a direction perpendicular to a plane of the substrate, at least one of the at least one first light-emitting element at least partially overlaps with at least one of at least one of the at least one first pixel circuit or the first driving circuit.
The invention relates to display panel technology, specifically addressing spatial efficiency and integration challenges in display designs. Traditional display panels often require separate areas for light-emitting elements and their corresponding driving circuits, leading to larger panel sizes or reduced pixel density. This invention improves upon prior designs by integrating at least one light-emitting element with at least one pixel circuit or driving circuit in a direction perpendicular to the substrate plane. The overlapping arrangement allows for a more compact layout, enabling higher pixel density or a thinner display without compromising performance. The light-emitting elements and circuits are positioned such that they share the same vertical space, reducing the overall footprint while maintaining functionality. This approach is particularly useful in high-resolution displays, such as those used in smartphones, tablets, or wearable devices, where space optimization is critical. The invention ensures proper electrical connections and optical performance despite the overlapping configuration, providing a balanced solution for modern display applications.
12. The display panel according to claim 11, wherein at least two adjacent second shift registers of the second shift registers are stagger from each other in a first direction, and the second direction intersects the first direction.
The invention relates to display panel technology, specifically addressing the arrangement of shift registers in display panels to improve performance and efficiency. The display panel includes a plurality of first shift registers and second shift registers, where the second shift registers are connected to the first shift registers. The second shift registers are arranged in a staggered configuration in a first direction, meaning that at least two adjacent second shift registers are offset from each other. This staggered arrangement helps optimize the layout and reduce interference between adjacent shift registers. The first direction is intersected by a second direction, which may correspond to the scanning direction or another relevant axis in the display panel. The staggered arrangement of the second shift registers can improve signal integrity, reduce crosstalk, and enhance the overall reliability of the display panel. This configuration is particularly useful in high-resolution or large-area display panels where precise control of shift register signals is critical. The invention aims to provide a more efficient and reliable display panel design by optimizing the spatial arrangement of shift registers.
14. A display device comprising the display panel according to claim 1.
A display device includes a display panel with a substrate, a plurality of pixels, and a plurality of light-emitting elements. The substrate has a first surface and a second surface opposite the first surface. The pixels are arranged on the first surface of the substrate, and each pixel includes a light-emitting element. The light-emitting elements are configured to emit light in a direction away from the substrate. The display panel further includes a plurality of light-transmitting regions and a plurality of light-blocking regions. The light-transmitting regions are arranged between the light-emitting elements and the second surface of the substrate, allowing light emitted by the light-emitting elements to pass through the substrate. The light-blocking regions are arranged between the light-transmitting regions and the second surface of the substrate, preventing light from passing through the substrate. The light-blocking regions are positioned to block light emitted by adjacent light-emitting elements, reducing optical crosstalk between pixels. The display device may also include additional components such as a backlight or a touch sensor, depending on the specific implementation. This design improves display performance by enhancing contrast and color accuracy while maintaining high brightness.
17. The display panel according to claim 15, wherein the first driving circuit comprises a light-emitting driving circuit, and the second driving circuit comprises a scanning driving circuit.
A display panel includes a substrate with a display area and a peripheral area. The display area contains a plurality of pixel units, each having a light-emitting device and a first driving circuit connected to the light-emitting device. The peripheral area includes a second driving circuit electrically connected to the pixel units. The first driving circuit is configured to drive the light-emitting device, while the second driving circuit is configured to control the pixel units. The first driving circuit is a light-emitting driving circuit that regulates current or voltage to the light-emitting device, ensuring consistent brightness and efficiency. The second driving circuit is a scanning driving circuit that sequentially selects pixel units for data input, managing the timing and synchronization of display operations. The substrate may be flexible, and the display panel may include a flexible encapsulation layer to protect the components. The light-emitting device is typically an organic light-emitting diode (OLED), and the driving circuits are integrated into the substrate using thin-film transistor (TFT) technology. This design improves display performance by separating the driving functions, enhancing reliability and efficiency in flexible or high-resolution displays.
